The production of perfluoroalkylsulfonate (PFOS) derivatives from linear alkyl precursors using electrochemical fluorination is not a clean process but, instead, gives complex mixtures. This study reports the isolation and (19)F NMR characterization of eleven perfluorooctanesulfonate isomers from a commercial mixture. This allowed the quantification of the individual CF(3) branched isomers that predominate in technical PFOS.
使用电化学氟化法由直链烷基前体生产全氟烷基磺酸盐（PFOS）衍生物并非一个清洁的过程，相反，会产生复杂的混合物。本研究报告了从一种商业混合物中分离出十一种全氟辛烷磺酸盐异构体并对其进行（19）F NMR表征。这使得能够对工业级PFOS中占主导的各个CF(3)支链异构体进行定量分析。
